What is the speed of sound in dry air at 0°c?

331.31 m/s

Explanation:

The speed of sound in air is given by,

where γ = ratio of molar heat capacity of the gas  (1.401 @ 0 °C)

           R = Universal gas constant ( 8.314 J/ molK)

           T =  absolute temperature (kelvin temperature) (273 K)

           M = molar mass of gas (28.97 g/mol)

using these values,

         = 331.31 m/s
